REAMER ATTACHMENT FOR DIE-STOCKS.

Specification of Letters Patent.-

P atented April 9, 1907.

Application filed April 20, 1906. SeriaLNo. 312,865;

fern, county of Rockland, State of New York, have invented certain new and useful Improvements in. Reamer Attachments for Die-Stocks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art towhich it appertains to make and use the same, reference being had to the accompanyin drawings, and to letters of reference marked thereon, which form a part of this specification.

'My invention relates to reamer attachments for pipe-cutting diestocks-; and it con: sists in certain im rovements having for their object to provi e a device of this nature which while being com aratively inexpensive in construction an effective in, operation is quickl and readily adjustable to different s1zes o pipes to be reamed and is, furthermore, in one specific form thereof adapt ed for use with either of two well known or standard forms of die-stocks. My invention will be found fully illustrated in the accom anying drawings,wherein Figure 1 s ows one form'of my invention applied to a die stock of the Armstrong. p view of the Fig. 1 detac is a top plan view of what is shown in Fig. 2 with a certain screw and washer detached. Fig. 4 shows another form of my invention attached to a die-stock, the stock being shown in section and aportion of a pipe being also illustrated. Fig. 5 is a top plan 'view, of the frame of my attachment shown in 4, and Fig. 6 illustrates a detail of said'framer In the drawings, a is the body of an Armparts of the invention shown in strong die-stock; b, its handles, screwed into the same in the usual manner .0, its dies, adapted to be adjustedor set by means of adjusting-{screws d and e, and f is the throat of the die-stock.

.g, in-Figs. 1,2, and 3, is a curved frame having inturned extremities h, provided with openings '5. Centrall of this frame is another opening j, which is referably square. Thisframe is adapted to e secured to the die-stock, as shownin Fig. 1, by means of the screws (1, which are made to enetrate the openings 1', and thereby bind t e extremities h to the stock.

Fig. 2 is a somewhat enlarged front.

ed from the die-stock. Fig. 3

whose extremities l,'which are tapped at m, are parallel with each other, at being a central hole in the frame corresponding to the hole j of frame g. This ty e of frame may be adapted to either the grmstrong ty e or any other type of die-stock, such as the d which may not have screws corresponding to the screws (1. The frame is attached in such instances by. screwing the handles 5 into the extremities l of the frame, as well as into the die-stock. (See Fig. 4..) p

o is a threaded stem having agroove p out therein lon 'tudinally thereof and also having a shou der q near one end. Said end issquared, as at r, so that it is adapted to fit the hole j (or n) of the frame 9, (or k.) In

In Figs. 4, 5, and 6 a frame It is illustrated aunders,

order to secure the stem to the frame, the

squared end of the stem is tapped to receive a screw s, acting. to binda washer t against the top face of the frame.

u is the reamer, the same being referably of rose form and having an interna threaded bore which receives the threaded stem 0. 'v-

is a thumb-screw carried by the reamer and adapted to engage-in the groove 1).

e attachment having been secured to the pipe. It'willbe understood, of course,

that further adjustment of the reamer will on the inside of the end of not be'necessary 1f pipes subsequentl to be threaded have the same diameter as t e first one.

Having thus what I claim as new, and desire tosecure by Letters Patent, is p The combination, with a pipe-cutting diestock, of a bowed frame attached thereto and having a non-circular opening formed axially of the die-stock, a threaded stem extending axially of the die-stock and having anoncircular end-fitted into-said opening-and a shoulder bearing against one faceof the frame, means, cooperating with said shoulder fully described my invention,

and bearing against the other side 6f the I have hereunto set my hand this 14th day 01 frame, for securing the stem in the frame, a April, 1906 reamer arranged on, and having threading engaging that of, the stem, and a screw car- 1 FRANK BARNES 5 ried y the reamer and adapted to bear 'VVitnesses:
